DETAILED DESCRIPTION OF TITLE INVENTION

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the various described embodiments. However, it will be apparent to one of ordinary skill in the art that the various described embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

Presented herein is an assembly that includes a number of conductors that a separated from one another and are encased or embedded within a substrate. The substrate defines a location feature. The substrate also defines an opening that has a predetermined size and shape. A section of the plurality of separated conductors is exposed within the opening. The opening is precisely located relative to the location feature. The assembly, particularly a portion of the substrate that defines the location feature and the opening, may be advantageously formed by an automated additive manufacturing process, e.g. 3D printing, stereolithography, digital light processing, fused deposition modeling, fused filament fabrication, selective laser sintering, selecting heat sintering, multi-jet modeling, multi-jet fusion, electronic beam melting, and/or laminated object manufacturing.

The examples presented herein are directed to assemblies in which the conductors are wire electrical conductors. However, other embodiments of the assembly may be envisioned wherein the conductors are fiber optic, pneumatic, hydraulic conductors, or a hybrid assembly having combination of any of these conductors.

FIG. 1 illustrates an example of an automotive wiring harness assembly according to an embodiment of this invention, hereinafter referred to as the assembly 100. The assembly 100 includes a plurality of wires 102 that are formed of an electrically conductive material, e.g. a metallic alloy, carbon nanostructures, and/or electrically conductive polymers. These wires 102 are separated from one another and are enclosed within, i.e. surrounded by, a substrate 104 that is integrally formed of an electrically, insulative material, e.g. a dielectric polymer. As shown in FIG. 2, the substrate 104 also defines an aperture 106 that extends through the substrate 104 and in which a section of the wires 102 are exposed. Referring again to FIG. 1, the substrate 104 defines a location feature 108, e.g. a fiducial mark, an edge, a corner, a notch, a slot, or a hole on/in the substrate 104, that can be used by a human operator or preferably an automated assembly robot (not shown) to determine the location of the aperture 106. The aperture 106 is precisely located relative to the location feature 108. As used herein, “precisely located” means that the position tolerance of the opening relative to the location feature datum is 1 millimeter or less. The position tolerance of the opening may be determined by the capability of the manufacturing technology and/or the capability of the automated assembly robot. This locational relationship between the location feature 108 and the aperture 106 provides the benefit of adding connectors or electronic modules to the assembly 100 using robots rather than requiring human assembly operators. The wires 102 are also precisely located relative to one another and relative to the edges of the aperture 106. As shown in FIG. 1, the substrate 104 surrounds the aperture 106. The exposed section of the wires 102 within the aperture 106 in this example have an electrically conductive surface that is not covered by an insulative jacket. The wires 102 are arranged and maintained by the substrate 104 in a predetermined order. In alternative embodiments, the exposed section of the wires 102 within the aperture 106 may be covered by an insulative jacket. As shown in FIG. 1, the assembly 100 includes several apertures 106 in which several subsets of the wires 102 are exposed. As further shown in FIG. 1, different sections of the same wires may be exposed in more than one aperture. This provides the benefit of allowing multiple connectors to be attached to the same wires. This may provide easy access to power or signal busses that are connected to more than one connector or electronic module.

This assembly 100 lends itself to being manufactured using an automated additive manufacturing process, such as 3D printing, stereolithography, digital light processing, fused deposition modeling, fused filament fabrication, selective laser sintering, selecting heat sintering, multi-jet modeling, multi-jet fusion, electronic beam melting, and/or laminated object manufacturing. The assembly 100 may be produced by the automated additive manufacturing process having a shape that is pre-formed to be placed within the packaging accommodation for the wiring harness within a vehicle. The assembly 100 is also well suited for robotic placement of the assembly 100 within the vehicle.

As illustrated in FIG. 2, the wires 102 may have different diameters depending on the current carrying capabilities required by circuits formed by the wires 102.

As illustrated in FIG. 3, the assembly 100 further includes a connector 110 having a lower support segment 112 disposed within the aperture 106 that is secured to the substrate 104 by a lower locking feature 114. The lower support segment 112 defines cradle features 116, shown in FIGS. 4 and 5, having a plurality of concave arcuate surfaces that contact a lower portion of the each of the wires 102, thereby supporting the wires 102 within the aperture 106. In alternative embodiments, the lower support segment 112 may be integrally formed with the substrate 104.

Returning to FIG. 3, the connector 110 further includes an upper connector segment 118 that is received within the lower support segment 112 and is secured to the lower support segment 112 by an upper locking feature 120. The upper connector segment 118 includes a plurality of terminals 122. The terminals 122 have a first end 124 that is in mechanical and electrical contact with the wires 102 and a second end 126 that is configured to mate with a corresponding mating terminal (not shown) to form an electrical connection with a separate electrical device (not shown), e.g. an electronic control module, a lighting module, an electronic sensor, and/or another electrical wiring harness. In alternative embodiments, the upper connector segment 118 may be integrally formed with the substrate 104 and connected to the substrate 104 by a living hinge. As illustrated in FIG. 3, the assembly 100 includes several connectors. The terminals 122 in one of these connectors may be connected to wires 102 common with the terminals 122 in another connector 110. Alternatively, one of these connectors may not include terminals 122 that are connected to wires 102 common to any of the other connectors.

As illustrated in FIG. 7, the first end 124 of each terminal 122 defines a forked end 128 that has two tines 130. A wire 102 is received between the two tines 130. The walls of the two tines 130 are angled so that the two tines 130 are in compressive contact with the wire 102 when the upper connector segment 118 is fully seated within the lower support segment 112. In alternative embodiments in which the exposed section of the wires 102 within the aperture 106 is covered by an insulative jacket, the two tines 130 are also configured to cut through and displace the insulative jacket so that the terminal 122 can make compressive electrical contact with the wire 102 within. As shown in FIG. 5, the lower support segment 112 defines a plurality of recesses in which the ends of the two tines 130 of the plurality of terminals 122 are received. The cradle features 116 of the lower support segment 112 support the wires 102 to inhibit bending of the wire 102 as the wire 102 is received within the two tines 130 of the terminal 122 and the two tines 130 come into compressive contact with the wires 102.

In an alternative embodiment of the assembly 100, the wires 102 have a coating that is formed of an electrically conductive material (e.g. pure tin or a tin-based solder) that has a lower melting point than the conductive material forming the wires 102. The terminals 122 are metallurgically bonded to the wires 102 by a soldering or welding process due to localized heating of a portion of the coating. This heating may be performed using a laser, resistive heating of the terminal 122 and the wire 102, application of a soldering iron, or other means.

In alternative embodiments of the assembly 100, the upper connector segment 118 may be replaced by an upper modular segment that itself contains a relay, an electronic controller, an electronic sensor, a lighting device, and/or other electronic devices. The upper modular segment includes terminals 122 that have the first end 124 that is in mechanical and electrical contact with the wires 102 but the second end of the terminal is directly connected to circuitry or electrical or electronic devices within the upper modular segment rather than corresponding mating terminals.

As shown in FIGS. 6 and 7, the lower support segment 112 defines a lower lip 132 that extends laterally from the lower support segment 112 and engages a lower surface of the substrate 104 around a perimeter of the aperture 106. The upper connector segment 118 likewise defines an upper lip 134 engaging an upper surface of the substrate 104 around the perimeter of the opening. The lower and upper lips 132, 134 sandwich the substrate 104 therebetween to further secure the lower support segment 112 within the aperture 106. This provides the benefit of limiting longitudinal movement of the connector 110 within the aperture 106.

The lower lip 132 defines a lower groove 136 that contains a lower seal 138 that is formed of a compliant material (e.g. a silicone rubber). The lower seal 138 engages the lower surface of the substrate 104 around the perimeter of the aperture 106 and seals the interface between the lower support segment 112 and the substrate 104 to inhibit intrusion of contaminants, such as dust and fluids, into the aperture 106, thereby protecting the terminals 122 and the wires 102 within the aperture 106. The upper lip 134 similarly defines an upper groove 140 that contains an upper seal 142 that is also formed of a compliant material, such as silicone rubber, that engages the upper surface of the substrate 104 around the perimeter of the aperture 106 and seals the interface between the upper connector segment 118 and the substrate 104 to inhibit intrusion of contaminants into the aperture 106, thereby protecting the terminals 122 and the wires 102 within the aperture 106. A single seal design and construction may be used for the lower seal 138 and the upper seal 142 in order to provide the benefit of reduced number of unique parts in the assembly 100.

In alternative embodiments of the assembly 100, the assembly 100 may further include a first inner seal 135 that is located intermediate the lower support segment 112 and an inner surface of the aperture 106 that engages both the lower support segment 112 and the substrate 104. The assembly 100 may also include a lower seal 138 that is formed of a compliant material and sealingly engages a lower inner surface of the substrate 104 within the aperture 106 to inhibit intrusion of contaminants, such as dust and fluids, into the aperture 106. The first inner seal 135 may be used in addition to, or instead of, the lower seal 138. In this or other alternative embodiments, the assembly 100 may additionally include a second inner seal 139 that is formed of a compliant material located intermediate the upper connector segment 118 and the lower support segment 112 to further inhibit intrusion of contaminants into the aperture 106.

As shown in rig. 4, a first region 144 of the substrate 104 surrounding the opening is thicker than a second region 146 of the substrate 104 remote from the opening. This greater thickness of the substrate 104 in the first region 144 than the second region 146 provides increased stiffness in the first region 144 relative to the second region 146. The increased stiffness in the first region 144 around the aperture 106 provides the benefit of a secure connection between the connector 110 and the substrate 104 while the decreased stiffness in areas remote from the aperture 106 allow the assembly 100 to flex in order to be installed within a vehicle. There may also be other regions of varying stiffness in the harness. These variations may provide benefits of providing mounting features or reducing the probability of the assembly 100 rattling when installed in the vehicle.

In alternative embodiments of the assembly 100, the increased stiffness in the first region 144 relative to the second region 146 may be provided by the substrate 104 being formed in a particular shape, e.g. including a stiffening rib or beam. The stiffness may also vary due to differences in the structure of the material, e.g. a lattice structure vs. a solid structure, differences in thickness of the material, or use of different polymer materials having different stiffness properties e.g. polyamide and polypropylene.

In alternative embodiments of the assembly 100, the substrate 104 is a structural portion of a motor vehicle 147, such as a headliner, trim panel, body panel, floor liner, or hood liner as shown in FIG. 9.

As shown in FIG. 4, the assembly 100 also includes attachment features 148 that are incorporated into the substrate 104. These attachment features 148 may be used to secure the assembly 100 to the structural portion of a motor vehicle 147. The attachment features 148 may be integrally formed by the substrate 104 or they may be discrete parts that are incorporated into the substrate 104 during the forming of the substrate 104 by forming the substrate 104 around a portion of the attachment feature 148. The attachment features 148 shown in FIG. 4 are eyelets that receive a stud, bolt, push pin or other attachment device having a shaft and a head. In alternative embodiments, the attachment features 148 may be smooth studs, treaded studs, barbed pins, “fir trees” or other attachment features 148 known to those skilled in the art.

Also presented herein is an apparatus that can be used to manufacture the assembly 100 described above. FIG. 10 illustrates an 3D printing apparatus according to an embodiment of the invention, hereinafter referred to as the apparatus 200. The apparatus 200 includes an extruding device 202 with a dispensing head 204 that selectively dispenses a dielectric thermoplastic material though an orifice 206 in the dispensing head 204. The thermoplastic material may be provided to the dispensing head 204 in the form of a thermoplastic filament, as used in filament deposition modeling, thermoplastic pellets, or a thermoplastic powder.

The apparatus 200 also includes a wire feed device 208 that selectively feeds an electrically conductive wire, hereinafter referred to as the wire 102, through the orifice 206. A cutting device 210 that is configured to selectively sever the wire 102 after it passes through the orifice 206 is also included in the apparatus 200. The wire 102 may already be surrounded by an insulative jacket prior to passing through the orifice 206.

The processors may be a microprocessor, application specific integrated circuits (ASIC), or built from discrete logic and timing circuits (not shown). Software instructions that program the processors may be stored in a non-volatile (NV) memory device (not shown). The NV memory device may be contained within the microprocessor or ASIC or it may be a separate device.

The memory device contains instructions that causes the electromechanical device 212 to move the extruding device 202, the wire feed device 208, and the cutting device 210 within the 3D space. The instructions also cause the extruding device 202 to selectively dispense the dielectric material though the orifice 206. The instruction further causes the wire feed device 208 to selectively feed the wire 102 through the orifice 206 and cause the cutting device 210 to selectively sever the wire 102.

The memory device may further contain instructions that causes the extruding device 202 to selectively dispense the dielectric material though the orifice 206 as the electromechanically device moves the extruding device 202 in the 3D space to form the substrate 104. The instructions additionally cause the wire feed device 208 to selectively feed the wire 102 through the orifice 206, and the cutting device 210 to selectively sever the wire 102 as the electromechanically device moves the wire feed device 208 and the cutting device 210 in the 3D space to form a plurality of wires 102 formed of the wire 102 that are subsequently encased within the substrate 104 by the extruding device 202. The instructions further cause the electrotechnical device and the extruding device 202 to define a location feature 108 in the substrate 104 and define an aperture 106 in the substrate 104 which has a predetermined size and shape in which a portion of the wires 102 is exposed. This aperture 106 is precisely located relative to the location feature 108.

According to an alternative embodiment of the apparatus 200, the apparatus 200 further includes a 3D curved surface 216 upon which the extruding device 202 selectively dispenses the dielectric material and the wire feed device 208 to selectively deposits the conductive wire. This 3D curved surface 216 provides the benefit of forming the assembly 100 with a predetermined shape.

This alternative embodiment may also include a heating device 218 in communication with the electronic controller 214 and is configured to heat a portion of the 3D curved surface 216. The memory device further contains instructions that causes the cooling device 220 to selectively heat the portion of the curved surface 216. This feature provides the benefit of heating the thermoplastic material while forming the substrate 104 in order to produce a desired shape or material properties.

This alternative embodiment may additionally or alternatively include a cooling device 220 that is also in communication with the electronic controller 214 and is configured to cool a portion of the 3D curved surface 216. The memory device further contains instructions that causes the cooling device 220 to selectively cool the portion of the curved surface 216. This feature provides the benefit of cooling the thermoplastic material while forming the substrate 104 in order to produce a desired shape or material properties. The heating device 218 and the cooling device 220 may be the same device, e.g. a thermoelectric device.
